Application led March 19, 1915. Serial No. 15,508.

To all whom it may concern:r

13e it known that', DEWEY D. STEPHENS, a citizen of the United States, residing at Ainsworth, in the county of TWashington and State of Iowa, have invented certain new and. useful Improvements in Seeders and Harrows,of which the following is a speciiic'ation, reference being had therein to the accompanying drawing.

The invention relates to a combined seed'- ing and harrowing mechanism in the construction of which use can be made of ar harrcw of standard construction.

The objects of the invention, therefore, are to provide a combined mechanism of the class referred to and also to provide a feeding mechanism which is adapted to be com? bined with a harrow in theway described.

Of the drawings which illustrate one em-A bodiment of the invention,

Figure 1 is a plan view;

Fig.l 2 is a side view partlyin section along the line 2-2 of Eig.l 1;

Fig. 3 `is an enlarged side vView of the seeder part of the mechanism.

Referring to 'the drawings, 1 represents7 as a whole, the harrow which is of the toothed class. As concerns'the details of the har-row, it will be understood that there can be wide variation without departing from the spirit of the invention. But in order that one embodiment of the invention may be clearly understood I will describe the particular harrow which has been selected for purposes of illustration. The harrow is of the spike toothed variety, there being four tooth-carrying frames 2-2. Each frame is made up of transverse bars 3, 3, preferably of wood, and longitudinal bars 4, 4, preferably of metal and extending through suitable apertures in the wooden bars 3, 3. Vertical spikes 5eXtend through the bars 3 and 4 and have their lower ends sharpened to engage the ground. The four frames 2-2 arearranged in pairs, and those of each pair are connected by means of suitable chain links 6, 6 with a transverse drag bar 7. The two drag bars'7, 7 are, in turn, connected vby means of suitable links or eyes 8, 8 with a transverse drag bar 9. To the drag bar 9 are connected suitable double trees 10 and swingletrees 11 for the attach ment of two pairs of horses.

A suitable truck 12, having two ground wheels 13, 13, carriesadrivers seat 14..A The truck 12 is connected with the forward parts of the harrow, preferably with the drag bars 7, 7 by means of forward extending diverging rods or bars 15,15.I lfhese are connected with the drag bars 7, 47 by means of hori- Zontal pivots at 16, 16.`

The seeder part of the mechanism is detachablel from the harrow part above described, and it will be understood that the harrow can bc used independently of the seeder when desired. As concerns the details'of construction, the seeder mechanism can be of any one of a number of forms, and

the invention is not'limited to the exact con- A portion 2O which is secured rigidly to the seed'boX. The upright 19 preferably has a number 'of apertures` therein through any one of which can be inserted a pin 21 for connecting the upright with thel draft rod l5. lBy this construction the inner end of the seed boX can be raised-or loweredV as desired. A brace 22 extending'forward to the draft rod 15 serves to hold the upright 19 against turning about the pin 21.

The outer end of each seeder mechanism is connected with the outer' end of the corresponding drag bar 7 by means of a link 23. Each bar carries at its outer end a pivot pin 24, with which the forward end of the'corresponding link engages. Each stud'axleon vwhich the corresponding ground wheel 18 is mounted "is provided with an eX- tension 25 with ywhich the lrear end of the corresponding link engages..

As concerns the devicesfor measuring and discharging the seedsy from'the boX at 7, there can be wide variation. For purposes of illustration I have shown a transverse rotatable shaft 26, driven from the corresponding ground wheel 18 by means of sprocket wheels 27 and 28 anda chain 29. By means of a cam 30 and a rocking lever 31, an apertured feed plate 32V extending longitudinally of the seed' box is reciprocated. The bottom of the box is pro-vided with apertures with which the apertures in the bar 32 can register. When registration takes place during reciprocation the seeds flow out and i are discharged to the ground through seed tubes such as are indicated at 33 in Fig. 3.

From the foregoing description it will be seen that 1 have provided a seeder mechanism which is so connected to and correlated with the harrowing mechanism that both can be operated simultaneously. The parts arek so arranged that the front row of harrow teeth first breaks and loosens the'soil. After the front row of teethhas passed over the ground the seed is deposited on topv of it from the seeder mcchanisnji. rllhen the rear rows ofi harrow teeth engage the soil and further break it up and loosen it, at the same timeI raking' the seed into it.

The connections of the inner ends of the seeder mechanisms to the draft bars 15, 15 are sufficiently loose to permit relative rising and falling movements of the outer ends as the wheels18, 18 follow the ground surface.

Y:lo

The connection of the outer ends ofthe seeder sections to the harrow through the links 23, 23 permits relative independence of movement vertically, thus insuring` the full weight of the outer parts of the seeder sectionson the wheels to give sufficient draft' force to turn the wheels and operate the mechanical parts of the seeder.

By' making use of the truck 12 and its draft bars 15, 15 1 am enabled to eliminate any supplemental supports for the inner ends of the seeder sections, thus greatly simplifying the construction. The whole mechanism is flexible so that irregularities of the ground can be followed closely, the harrow being formed in four sections each independentlyH movable vertically and the seeder being formed in two sections each independently movable vertically. The truck 12 and the draft bars 15 not only serve to support and hold the driver, but also serve to support th'e inner ends of the seeder mechanisms and to carry them Vat la uniform distance from the ground even though the ground surface'may be'irregular and uneven.

Vfhat I claim is:v

1. The combination of a toothed hai-row, a drivers truck, aseeder mechanism extending transversely of the harrow from one side to the other between the front and rear edges thereof, the seeder mechanism being constructe'dv in two sections each supported at its inner end in part on the drivel-s truck and each having at its outer end a groundengaging `supporting and driving wheel, and
